Line 13: − − The same basic circuit design will go into the amplifiers of the tagger microscope amplifier boards. A separate, second-stage driver will be added to feed the summing circuit (fiber array is read out in groups of 5 channels).

A similar amplifier circuit will be designed for every SiPM channel on the board. Those corresponding to a single column will be summed at some stage. Each board, however, will have the capacity for a column of independent channels, since the design of the tagger calls for five such columns in the array.

Each board, however, will have the capacity for a column of independent channels, since the design of the tagger calls for five such columns in the array.
A compromise will be found between fewer boards with more channels (up to 32, given the DAC's limitation) and more boards with fewer channels. The former options may yield cost savings and provide easier maintenance with more space inside the tagger box. On the other hand, a clean design with many channels per board may be difficult both from electronic and light-coupling standpoint.
A separate, second-stage driver will be added to feed the summing circuit (fiber array is read out in groups of 5 channels). The passive components of the circuit are being optimized for tagger use:
